To all whom it may concern:

Be it known that I, FELIX MANIER, a citizen of the United States, and residing at No. 529 West High street, in Piqua, in the county of Miami and State of Ohio, have invented certain new and useful Improvements in a Combined Nut and Pipe Wrench, of which the following is a specification.

My invention pertains to that class of sliding-jaw wrenches wherein each jaw and a handle form a one piece part, and by which one piece parts the wrench is adjusted.

My invention has for its object, to provide a non-sticking wrench with great leverage, which is simple'in construction, positive in action and admits of quick adjustment.

Other objects and advantages will be apparent from-the following description.

In the drawings, Figure 1 is a sectional view along the line H of Fig. 2. Fig. 2 is a side elevation with parts broken away showing the position of the dog C andthe spring G and Fig. 3 is a side elevation with the jaws-separated andthe handles spread.

Referring to the drawings wherein like characters represent the same parts throughrated surface F attached thereto by means.

out, A represents the outer jaw with the shank and handle A, and with a transverse opening A through the shank part thereof, and in which transverse opening the dog 0 is operated. Said upper aw A'has a serof the screw 72.

B. represents the inner jaw with the handle, with a longitudinal opening therein and therethrough, and through which longitudinal opening said handle and shank part A" of the jaw A passes. Said lower jaw is provided with the serrated surface F attached thereto by means of the screw I). Said jaw B has pivoted thereto at E in said longitudinal opening and fitting in said;

with a pin D, which pin D extends therefrom out through the opening D in the wall of the jaw B. By means of saidpin D when the handles A. and B are spread the teeth C are released from in mesh with the teeth A and either the jaw A or the jaw B may be operated out or in at the will of the operator to adjust the wrench to the size of the nut or pipe to be operated upon. The jaw B is cut away at H inorder to permit ofthe spreading of the handles A and B as indicated in the Big. 6 of the drawings.

- It will be readily noticed that in the wrenchdescribed the fulcrum oint is at all times from under any part of t e nut or pipe being operated upon and by reason thereof the wrench is rendered non-locking. B non l0cking is meant a wrench that is rea ily and easily released from engagement in operating upon a nut or pipe. The wrench described will operate upon and can be released from operation on, readily and quickly, any sized nut or pipe. It will-be further noticed that the same amount of leverage is obtainable on large nuts or pipes as on small ones. This same degree of leverage is obtained by reason of the handle B 'actingas a lever the lower end thereof being at all times the same distance from the point of fulcrum. Thisis not true in other wrenches. In other wrenches the larger the nut or pi e the less the leverage. v It will also be notice that the more power is applied to the lever handle B the more firmly the. nut

or pipe operated upon is held.

Having fully described'my invention [so that others skilled in the art can make the to secure, by

her provided with a transverse slot, having a jaw portion provided with serrations coactmg with said first-named serrations, a handle portion and a pivot portion; a pin pass.- ing'through said slot and pivot portion causing the serrations of the movable member to swing angularly with respect to the serrations of the' stationary member when said' movable member is swung on-said pin, and

causing the serrations of the movable member to move bodily to and from the serrations of the stationary member when the pin of said movable member is moved up and down in said slot; a pawl havin adapted to engage said first-name 110 Q emme ivoted on said in, and ada ted to swing In testimony whereof I hereto affix my mdependently 100 said movab e lmemger; 3 signature in presence of two Witnesses in passin t roug said aw an sai n ransverse s lot in the said m vable member; FELIX MANIER and a spring controlling said pawl located Witnesses: in said transverse slot, substantially as de- E.
